Reserved Seating at Movies: Yay or Nay?

Yesterday we detailed the changes at the newly renovated Cinerama—among them reserved seating. Which sparked a mini-debate in the comments. On one side, you’ve got those who think the system can make it difficult to find multiple seats together. And on the other, you’ve got those who love the security that comes from knowing they don’t have to get to the theater half an hour early just to snag the perfect spot.
After the recently renovated Sundance Cinemas in the U District, Cinerama is only the second theater in Seattle to offer the service. So what do you think? Thumbs up or thumbs down?
